That is the technology we had before the LCD displays. It was nasty on your eyes, often gave you static electricity shocks and your phone would distort the image if it was placed close to the display, so you knew to pick up your phone before it rings or you had the message lol I still have one in my room, along with my 2 dead LCD's lol Ohh.... If one of those displays have a smashed screen, they could blow up and even eletrocute you from 5 meters away! Hurts like fuck when that happens lol LCD's are much safer....
